Coupling between lower‐tropospheric convective mixing and low‐level clouds: Physical mechanisms and dependence on convection scheme

Journal of Advances in Modeling Earth Systems, 2016
Several studies have pointed out the dependence of low‐cloud feedbacks on the strength of the lower‐tropospheric convective mixing. By analyzing a series of single‐column model experiments run by a climate model using two different convective ...

Satellite observations of convection and their implications for parameterizations

, 2015
Parameterization development and evaluation ideally takes a two-step approach (Lohmann et al., 2007). Insight into new processes, and initial parameterization formulation should be guided by theory, process-level observations (laboratory experiments or field studies) or, if these are unavailable, by high-resolution modelling.

River Ice Processes Modelling: A Comprehensive Review

River Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

A Parameterization for Cloud Organization and Propagation by Evaporation‐Driven Cold Pool Edges

Journal of Advances in Modeling Earth Systems
When the negatively buoyant air in the cloud downdrafts reaches the surface, it spreads out horizontally, producing cold pools. A cold pool can trigger new convective cells. However, when combined with the ambient vertical wind shear, it can also connect

Predictability associated with convection-allowing and convection-parameterizing forecasts

, 2018
Exponential increases in computing power during the last 30 years have allowed operational numerical weather (NWP) models to steadily refine their grid-spacing to better represent topographic features and related physical processes. The reductions in model grid-spacing have contributed to significant improvements in forecasts of many important ...

Analysis of flood events in the Three Gorges Reservoir Region using the coupled VIC‐CaMaFlood hydrological model

River, EarlyView.
Abstract In recent years, the Three Gorges Reservoir Region (TGRR) has been increasingly affected by climate change, with frequent flood events posing challenges to regional flood control. The NO.1 flood of the Daning River in 2024 further highlights the severity of flood risks in the region.

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace

steel research international, EarlyView.
This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.

Extreme rainfall in southern China in April 2024 and its potential link to weather events across south Asia

Weather, EarlyView.
This study documents the unseasonal and prolonged heavy rain events which occurred in southern China during April 2024. In this series of extreme rainfall events, Guangdong province recorded extreme rainfall exceeding 6‐sigma of climatology, with eleven cities reporting record‐breaking rainfall.

Targeted behavioural and microclimate data collection substantially improves biophysical model predictions of energy expenditure in wild birds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Energy is fundamental for life and accurately predicting animals' energy expenditure under changing environments is central to ecology and global change biology. Energy expenditure in free‐living animals can be directly quantified using the doubly labelled water (DLW ...

Balancing Convective and Langmuir Turbulence: An Enhanced Mixing Scheme for Ocean Models

Oceans
Langmuir turbulence is a key and common process in the ocean surface boundary layer, playing a major role in vertical mixing, heat flux, and material transport.
